Police believe the driver of the vehicle carrying members of Mexican Banda music group La Reyna de Monterrey fell asleep at the wheel around 8 a.m. local time. The vehicle crossed into the other lane where it crashed head on with a tractor-trailer.

The force of the impact threw band members from the vehicle onto the highway connecting Monterrey and Nuevo Laredo.

The band members, aged between 20 and 25, had given a concert in the border city of Nuevo Laredo in Tamaulipas state on Friday night.
